Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and bioactive compounds. It serves as a protecting group for amines, allowing selective reactions to occur without affecting the amine functionality. Commonly employed in peptide synthesis, where it helps in the stepwise construction of peptide chains. Also utilized in the development of drug candidates, especially in the modification of amine-containing molecules to enhance their stability or bioavailability. Its applications extend to the production of agrochemicals and fine chemicals, where precise control over chemical reactions is essential.
